Define drone. Because if you want wand slowly shifting timbres it’s as simple as taking a couple slightly detuned oscillators and slowly sweeping some wave-shaping parameters, maybe running it through a filter, and drenching in reverb.
As far as making then evolve over time, you can crossfade different type of waveshapers and wet effects to create a variety of overtones ambient spaces. LFOs modulating LFO’s also gives your ear something to be interested in.
I encountered Riemann through Gill Deleuze’s use of his concept of multiplicity and several other ideas. Can you tell me what the connection is, as I am assuming the namesake for the clock is: https://en.wikipedia.org/wiki/Bernhard_Riemann
I built a module a while back modeled after the Ornaments & Crime Eurorack module which included this transform. It’s a method of chord progression which only move one note of the triad at a time. Makes for some interesting variations. If you use it as a way to change the underlying chord periodically it can add some movement to a background. I’ll post the module when I get a change to get back on the Mac. It should still be on the old forum.
My iPad mini 4 can’t run this without crackling. If only they had made an iPad pro in a smaller size! I had to choose b/w size and processing power, and went for size. It’s funny because it is slower than an iPhone 6. But here we are with iPhone X but no fast mini? Idiots. Make the chips upgradable and save us from disposable culture…
